Hey friends! If you’re curious about how insemination and fertilization work, you’re in for a treat. When it comes to IVF, there’s a lot happening behind the scenes in the embryology lab. Once eggs and sperm are collected, a meticulous process begins to ensure everything goes smoothly. This includes having two certified embryologists present at key moments to minimize any chances for mistakes.
After the collection, the eggs hang out in a special culture medium for a few hours. This medium is packed with essential nutrients that help the embryos thrive. Then, usually in the afternoon after egg retrieval, sperm is added to this mix in a process known as insemination. A few hours later, fertilization takes place when a sperm successfully penetrates an egg.
Once the egg and sperm unite, they start developing into an embryo, which divides rapidly. By days 5 or 6, these embryos are called blastocysts and can reach up to 100 cells! There are also some extra lab techniques that can be used to promote healthy embryo growth. Your doctor might suggest specific procedures based on your situation.
Techniques to Promote Healthy Embryo Growth
For instance, assisted hatching is a cool technique that helps embryos break free from their outer shell to implant in the uterus. Then there’s Intracytoplasmic Sperm Injection (ICSI), where the embryologist picks the best sperm and injects it directly into an egg, which is super helpful for certain male fertility issues. If you’re interested in learning more about ICSI, check out our detailed post.
Also, there’s Preimplantation Genetic Testing (PGT), which can identify genetic issues before the embryos are implanted. This might be a good option if you have a family history of certain genetic conditions or have experienced multiple miscarriages. A few cells are taken from the embryo and sent off for testing, which helps in selecting the healthiest embryos for transfer.
Cryopreservation Options
If you’re thinking about future options, our lab has a cryopreservation program for freezing eggs, sperm, and embryos. This can be a smart move if you want to preserve fertility for later. For instance, egg freezing can be a great choice if you want to take a break after egg retrieval or control the timing of your IVF cycle.
Men can also freeze sperm samples for later use, eliminating the need for additional collection procedures. And if you end up with extra high-quality embryos, those can be frozen too, making future IVF cycles a lot more affordable and less involved.
